has been heretofore experienced by reason of the loom weaving doubles, shives, misnottaking' up the hair.

picks and the like, causedby reasonof the selector of theihair cloth loom missing and To obviate the -toregoing "objections,

have-devised a novel construction of auto -mati ca1ly opera-ted pawl mechanism coacting with the acquard cylinder, wherebywhen the selector of the haircloth loom misses a hair, certain mechanism will be automatically operated so as to stop the rotation of the jacquard cylinder, whereby mispicks',

shives and doubles will be prevented.-

' It further consists of a novel construction and collocation of a disk, an arm carried thereby, connectionsfrom said arm leading to a movable pawl coacting with a jarquard cylinder a-nd'connections leading from said disk to a hair cloth loom, whereby when the selector of the latter misses a hair the rotation of the jacquard cylinder will be automatically stopped.

' It further consists of other novel features of construction, all as will be hereinafter fully set forth. V

For the purpose of illustrating my invention, I have shown in the accompanying drawings a form thereof which is at'present preferred by me, since it will'give in prac- V by my novel mechanism the difliculty hereto fore experienced by reason "of the loom weaving-doubles, shives', mis'picks and the tice satisfactory and reliable results, althoughit is tobe understood that the variousinstrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.- I,

- I have also refrained from explaining'in deta l the construct on and mode of operaknown' to those skilledin thisart, and, the

present disclosure is directed to the novelcoacting elements common to the loom and acquard mach ne, wherein I have overcome like, because of the selector'missing"and not taking up the hair, whereln 1 designates tion of the'jac uard machine as this'is well 7 tightandloo'sepulleys land '5, andthe bevel pinion 6, which'is in meshwith' the bevel gear 7 from which poweris transmitted to thejg'ear 8 mounted on the shaft 9,

said shaft carrying the cam 10, which: actuate's the'ca-m bar 1 1, which isprovide'd with the pendant-thig- 12, coactmp; w1ththeworking face ofthe cam 10. ;The camfbar '11 has one end pivotally' mounted 12 'upon the arm 13, the pposite end of said cam bar being guided in the U-shap'ed Ways '15. From the gear 8 power is transmitted to operative parts of the loom, but as those are old and form no part of the ,presentinven- 1 tion, I have deemed it unnecessary to describe the same in detail;

16' designates a vertically movable rod,

whose lower end isrpivo'tally connected to the dagger 17 havingthe angular or inverted V-shaped recess 18, which coacts with the similarly shaped lug 19 on the top of the cam bar 11, the'end of said bar being provided with the slot 14 through which passes the downward extension 12*of the dagger 17, said bar being pulled towards said cam 10 by means of the spring 10*. The upper end of the vertically movable rod 16 is pivoted at 20 to the arm 21, which issecured to,

the disk orv plate 22 by means'of the screws of bolts 23. I

The arm 21 has the upper end of the spring 24 attached thereto, the lower end of said spring being attached at the point 25 to the frame '26, so that a downward tension is exerted on said arm and itsadjuncts. The disk or plate 22rotates upon the pin 27 carried by thebar 27 supported on the upright frame 26 and is provided with the curved slot 28 through which projects the stationary pin or stop 29,- it beingjapparent that said stop serves to arrestthe rotary move- ,ment of said disk or plate 22 in each of its extreme positions.

V manner.

30 designates a connection or cable which is pivotally secured at the point 31 to the outer end of the arm 21, said connection 30 passing over the roller 32, which is rotatably mounted on the bearing 33.

' The upper end of the cable 30 is attached at the point 34 to the pawl 35, which is pivotally mounted at the point 36 in the arm 37 of the'bracket 38, which issecured to the.

attached to the fixed point 43. The pawl 35 is provided with a recess 44, whose Walls are adapted to engagethe corners of the jac quard cylinder3l, over which the cards 45 l of the usual construction pass in the usual known manner.

7 of picking mechanism and 48, the 'nipper manner. 7 V .7

'46 designates a trough or churn: for the hairs, whichmay be agitated in any well 47 designates the selector for picking up a hair'49 which is drawn across through the warp over the filling or hairwire 50 which action givessaid wire a sl ght downward movement;

The operation of the selectorand nipper seen in Figure is old in the art, and may be as disclosed in the patents heretofore referred to, hence I'have deemed it unnecessary to describe the same in detail, or to describe in detail the operation of the acquard mechanism 51 seen in Figures 2 and 3 and int the upper portion of Figure 1, which may also be of any conventional type, except to say that the cylinder 41 and its adjuncts are reciprocated. in. any well known manner, as

by the reciprocation of therod 52, which is suitably connected with the frame carrying the cylinder, 41, it being apparent that when the parts are inthe position 'seen in full lines in Figure 3, that each time the cylinder 41 is moved to the left in the direction of the arrow a, a corner as 53 of the jacquard cylinder 41 will engage the recess 44 of the pawl 35, and said cylinder will be givenya one quarter rotation in the direction of the arrow 5, which operation will continue 'until ice and the horizontal eye 56 located below the V lever 11, through which eye the downward extension 12 of the dagger 17 passes.

The operation is as follows The rotation of the cam 10 imparts .atthe proper intervals an up and. down movement to the lever 11. lVhen the selector 47 is ac -tu ated downwardly into the bunch of hairs in the churn 46 to pick up a hair, the nipper 48 grasps and drawsesaid hair across through the warp over thefilling or hair wire '50, whichgives'sa-id wire a slight downward movement, andrthe engagement of the eye 56 with the lower extension 12*. of the dagger 17 causes said dagger to move to the left of the position seen in Figure 6 in the direction of the arrow 0. Through the rotation of the cam 10, the lever 11 will'oscillate up and. down and whenthe dagger 17 and its adjuncts aremoved to the left of the position seen in Figure ,Gsothat the recess 18 is outof the path ofthe lug 19, the latter will have no function and the pawl 35 will remain in its initial-position seen in full lines in'Fig'ure 3 in'which'the recess 44 will engage with a corner 53 of the jacqnard cylinder 41-during its motion in the direction of the arrows, thereby causlng said cylinder to rotate a one-quarter turn. r

In the event that the selector a7 misses a hair, the hair Wire 50 will stay up causing the dagger 17 to assume the position seen in Figure 6.

. the position seen in full lines in Figure 4:

to the position seen indotted lines in said figure.

By this movement of the arm 21, the cable or connection will be pulled downwardly in the direction of the arrow (Z seen in Figure 8, and the pawl 35 will move from the position seen in fulllines in Figure 3 into the position seen dotted in said figure and out of the path of the cylinder- 41, thereby preventing. the jacquard cylinder 11 from rotating during its movement back and forth, since the recess 44: will be out of the path of a corner 53 of said cylinder.

The rotation of said cylinder will thus be automatically and 'instantly stopped and mispicks, shives and doubles will thereby be prevented. The slot 8 in the disk 22 and the pin or abutment 29 a-ctas stops to limit the movement of the disk 22, arm 21 and their adjuncts, and the tension of the spring 24: will hold the various parts under tension in their proper positions, as is evident.

It will be seen from the foregoing that by the employment of my novel features comprising the bar 27*, the arm 21, disk 22, spring 24, pin 29, cable 30, pulley 32, pawl 35, spring 12, and bracket 38 and their ad- 'juncts common to the jacquard machine and hair cloth loom, a novel and eflicient device for the purpose intended has been produced.
